That . That is probably a bit on the optimistic side. This would be something to discuss with the surgeon of course. A meniscal repair as opposed to a debridement would require a much longer period of rest because you want to give the repair a chance to work before you go back to putting your knee to work. If the meniscus is debrided back to a stable border (and not repaired) then there is nothing that would keep you from getting back on the trails even before 3 months.
